Hi l have two network the head office (site A : 192.168.1.0 ) and a small branch with 10 hosts (site B : 192.168.1.0).
i need to grant access to site A ressources, so we decide to buy a CISCO 881 for this remote office.
As you can see below the Wan interface is configured with ip adress (192.168.1.1 )
The local VLAN have 192.168.2.1 address.
After a telnet on the remote CISCO 881 l can ping all my servers on 192.168.1.0 /24 network.
But when l connect a computer (we can call pc1) to one of the fastethernet port (0 to 3) l can't ping the remote servers on site A ( but the router can )
Finally after waiting few minutes, the computer (pc1 : 192.168.2.10) can finally reach 192.168.1.0/24 hosts. when a second pc (pc 2 :192.168.2.20 ) is connected , the same issue came : pc2 can just reach the router WAN interface ( 192.168.1.1 ) but we can't ping servers on remote network ( 192.168.1.0 )
without any solution l tried this : l change pc2 IP address and give it pc1 address and also connected it to the same port as pc1
after these changes l can now ping remote ressources on 192.168.1.0/24 but pc1 can't now.
That's my first experience with 800 series router.
On site B l have 6 hosts and what l was trying to do is : connect all my hosts to a simple switch with 8 ethernet ports, and rely another port of this switch to one of my CISCO 881 fastethernet port ( which belong to VLAN1 by default ). But what l describe before is when the 2 pc are directly connect to cisco 881 switcports.
Please see my configuration below and tell me about your experience with this material (881)
did i miss something on my configuration or Cisco 881 have any particularity that l don't know ?
Thanks a lot for your assistance
